A review of African birds feeding in association with mammals Dean and MacDonald (1981), comprehensively document

of mammal and bird-feeding interactions. They report on the association of Brown Scrub-Robin Cercotrichas signata,

Robin-Chat Cossypha natalensis, and Chorister Robin dichroa feeding on insects flushed by foraging mole-rats

spp. in KwaZulu-Natal (Oatley 1970), and the association of Red capped Robin-Chat with Bushbuck Tragelaphus scriptus,

Cephalophus monticola, and cattle in forest (Oatley 1970) Oatley recorded, "In the Natal midlands forest I once

In this note we report on two additional observations of between Chorister Robin-Chat and Bushbuck.

1. On Friday, 15 March 2013, at 05:38, a video using a camera trap at Winterskloof, Hilton, 10

Pietermaritzburg, KwaZulu-Natal, in a section of mistbelt forest.

15 second snippet records a Chorister Robin-Chat flying directly onto the forehead of a female Bushbuck. It perches there for approximately 3 seconds, where it probes the right ear twice. The Bushbuck nods its head and the Robin-Chat hops onto the shoulders of the Bushbuck, where it perches for approximately 7 seconds the Bushbuck seems unperturbed. In the last section of the clip (where the recording is cut short) it appears as if the

near Pietermaritzburg, Mike Spain was conducting a bird walk and encountered a Bushbuck with a Chorister Robin-Chat perched on it back (K Nelson pers. comm. with M Spain, 2014). The bird did not glean from the Bushbuck but rather appeared to use the buck as a beater, waiting for it to disturb something edible when it would fly down and then back on to the buck; this it did at least twi (K Nelson pers. comm. with M Spain, 2014). Unfortunately no one in the group had a camera so details of the event were not recorded in detail.

Bringing together these observations suggests that the association, in particular, of these two species, may be more common than previously acknowledged, where Chorister Robin-Chats

Bushbuck as well as use them as "beaters". Indeed, the manner in which the Bushbuck appears comfortable with the Chorister Robin Chat visitor may even suggest that resident animals may have an

"understanding", or possibly the recognition of "cleaning stations animals.
